What do conducters and insulators do?

Answer 1

Voltage is the measure of electric potential, measure in volts.

Resistance, measured in ohms, determined the resistance to the flow of current through a material.

Current is the density of the flow of electrons past a point at a given time, and is measured in amperes (or amps).

Ohm's Law best describes this interaction: E (volts) = I (amps) * R (ohms)

So, voltage is equal to the amount of current (flow of electrons) flowing through a given substance times the resistance of flow of electrons.

Imagine a pipe through which water flows. The amount of water flowing through a pipe is the current (gallons per second...analogous to electrical current, which is measured in amperes = coulombs per second...a coulomb is a large unit of electrical charge). The resistance, in this case, would be the size of the pipe and the placement of any obstructions to the flow. If you place something at the end to hinder the outflow of the water, you will increase the resistance, and this increases the pressure (voltage is like electrical pressure). If you increase the size of the pipe, you reduce the resistance, but the current doesn't change.

If you leave everything the same and adjust a valve to reduce the flow of water, you will reduce the current (the flow), which also reduces the pressure at the end (the voltage).

Conversely, if you have a wire, and you hook up a battery to the two ends of the wire, you are introducing an electrical potential to that wire, which will induce a current on that wire. The better the electrons can flow through that wire, the lower the resistance. Put some electrical load or component in the path of those electrons, and you will increase the resistance slightly, thereby reducing the current of the wire.

Answer 2

In electronics, a conductor allows the flow of electrons and an insulator inhibits electron flow. In heat transfer, a conductor allows the transfer of thermal energy and an insulator inhibits the transfer of thermal energy.

Answer 3

An electric current can easily move through some materials. For instance, metals are good conductors. Another example, is the wires in most homes are made of cooper. This shows an electric current can easily move through some materials

Answer 4

A conductor is able to carry an electric current, whereas an insulator can't. However, it's not black and white. There are degrees of ability in both of these matters.
